Can mass of the lightest family gauge boson be of the order of TeV?
Abstract
The observed sign of a deviation from the e-μ universality in tau decays suggests family gauge bosons with an inverted mass hierarchy. Under the constraints from the observed K0-K¯0 and D0-D¯0 mixing, we investigate a possibility that a mass M33 of the lightest gauge boson A33 which couples with only the third generation quarks and leptons is of the order of TeV. It is concluded that M33∼1TeV is possible if we adopt a specific model phenomenologically.
